1 kilowatt of solar PV in Arizona produces an average of 1,718 kilowatt-hours of electricity per year, so a 8.0 kilowatt solar system would generate 13,744 kilowatt-hours of electricity every year. An average household in Arizona uses 12,333 kilowatt-hours of electricity in a year.


With an average state electricity price of 13 cents per kilowatt-hour, this solar system could save a household in Arizona $1,755 each year.
